ToaZZ whom it may concern;

Be it known that I, FRANK H. STANARD, a citizen of the 'United States,'residing at Kansas Gity,"inthe county of Jackson and State of Missouri, have invented certain new and useful Improvements in Gas Generators and Burners, offwhich the following is a specification.

" My invention relates to gas' 'generators" and burners, "andmy object is to'produce a comparatively simple and inexpensive "device of th1s character whereby hydrocarbon oils, such, for instance,- as kerosene can be vaporized and'intiniately'mixed with airto' produce an economical. and highly co'nf1hust1-' ble gas, whi'cliwlieni ignited produces a blue flame of intenseheat and free from cai'bon'. The device can be used to advantage inheat v ing and cooking stoves, furnaces, etc}, and in 'Figsiland 3. I The top wall 9 of the mixing and distriborder that the invention may be'tully'undenstood,,r eference will now be made to the ac companying drawing, in which:

Figure 1 is a plan view of aga's'generator and burner built inaccordance with my invention. i I

Fig. 2 is a central, longitudinalv section on line'II'II'of'Fig. 1f i Fig. 3 is a vertical, cross section, enlarged,

on line IIIIII of Fig. 2.

Fig. 4 is an elevation of a stabilizer employed in carrying out the invention.

In carrying out the invention, I employ a pan 1 in which the generator and burner proper rests. Said generator and burner embodies a longitudinal mixing tube '2, a.

mixing chamber 3 communicating with the discharge end 4 of said mixing tube, and a distributing chamber 5 communicating with and surrounding said mixing chamber.

The end of the mixing tube 2 most remote from its discharge opening 4, has oppositelydisposed air intakes 6 through which a'large volume of air is drawn to intermix with the vaporized oil. distributing chamber 5 is provided with legs 8 which rest in the pan 1, as disclosed by uting chambers 3 and 5, respectively, is preferably, cast in one piece and rests upon the side walls 10 of the distributing chamber, it being reliably held in place by bolts .11.

That portion of the top 9 above the mixing chamber 3, is preferably, higher than the portion above the distributing chamber 5 The bottom wall 7 of the.

and has downwardly flaring inner walls 12, which insure "thorough intermixing' of. the air and vaporized oil before they *e'sca'pet'o the distributing 'chamber, thetop-wall '9 of whichhas a central seriesofslits 13'and two side s'eries'of slits lt' 'for the" passageofthe ,"sp fieti n wi nfl if intent-sates. 18,1917- Applicationfiled-December 1@;. .91 ;'.:3 efla'1 1 .137,541. 1,

The vaporizing pipe 15'jis 'supported by-Ethe top wall 9 wofthe distributing chamberJSand also 'b y lu g s 1'1 projecting from thelongitudinal sides of chamber. 17 designates a' stabilizer communlcatlng With-'jthe pipe 15 t jin ure afsublstantially constant pressure therein 2 and thus avoid pulsation of the gas at the valve 16. Said stabilizer"comprises a tank connected at its lower end by a, nipple 18 to a T 19 to which the pipe 15 is connected. Said pipe 15 is provided at a. point between the stabilizer 17 and the source of .oil supply with a check valve 20, which opens toward the stabilizer and the burner to allow a free flow of oil thereto, but automatically shuts off any back pressure from the burner toward the fuel supply. A sight gage 22 communi-.

eating with the stabilizer indicates the height ,of the oil therein. Aside from its" connections with thenipple 18 and the gage 22, the stabilizer is hermetically sealed, so that as the oil enters therein from the pipe 15 the air in the stabilizer becomes compressed and exerts pressure upon the oil,

pressure, overcomes any back pressure from the burner and provides a steady'flow of 011 to the vaporizer p1pe'15.

the weight of which, combined with .said

V In" practice, a small amount ofoil is first placed in the pan 1 "and then ignited. The

flame thus produced heats the walls of the mixing tube 2 and the walls of the chambers 3 and 5, and also the pipe 15 thereby vaporizing the oil therein. The needlevalve at d. from the oil to di charge: from'the "16 is then opened to permit the vapor gen-,

valve nozzle 18 into the mixing tube 2. As the vapor discharges from the nozzle 18 with considerable force it draws in large volumes of air throughthe air, intakes ,6. This air commingles with the vapor in the mixing tube 2 and forms a highly combustible mixture, which on impinging against the top of 'the mixing chamber 3, is spread out in all parent that I have produced a gas generator and burner embodying all of the features above enumerated, and one which is economical in the consumption of fuel, owing to the'large volume of air utilized, and while I have shown and described the pre ferred form of my invention, I reserve the right to make such changes in the construction, combination, and arrangement of parts as properly fall within the spirit and scope of the claims.

Having. thus described my invention, what I claim and desire to secure by Letters Patent, is I I 1. In a device of the character described, a longitudinal mixing tube having oppositely-disposed air-intakes at one end and a i Washington, D. 0.

discharge opening at its opposite end, means for discharging vaporized 'oil into said mixing tube, a mixing chamber communicating with and located above the discharge opening in the mixing tube, a gas distributing chamber communicating with said mixing chamber and provided withopenings for the escape of the gas, and a vaporizing coil adjacent the openings in the distributing chamber and arranged to discharge into the said means for discharging the vaporized oil into the mixing tube.

2. A device of the character described, comprising a longitudinal mixing tubehaving oppositely-disposed air-intakes at one end and a discharge opening at its opposite end, a needle valve for discharging avapor into said mixing tube adjac'entits air-intakes, a mixing chamber arranged centrally over the discharge opening of the mixing tube provided with downwardly flaring walls, a distributing chamber communicating with and surrounding said ,mixing chamber and provided with slits for the escape of the combustible mixture, and a vaporizing pipe coiled about said distributing chamber adjacent the slits therein and communicating with theneedle valve, substantially as shown and described.

In testimony whereof I affix my signature,

in thepr'esence of two Witnesses.
